11,719. Alty, J. June 5. Water-waste preventers, siphon-discharge. Siphonic action is started by raising, in the cylindrical short leg A, a piston D having a turned-up rim and hinged to the rod F. The latter is connected to a pull-lever P, the fulcrum of which bears a stop H. The flow passes through apertures in the piston closed by hinged valves d, the spindles of which are retained in place by a bridge-piece k and a screw e, Fig. 3.
